Abstract:
A camera includes a data acquisition unit, a photographing area control unit, a photographing unit and a communication unit. The data acquisition unit acquires, as photographing information, at least one of time information, information on a position of the sun, information on an angle between a sunlight and a ground, and projection information of an external projection device. The photographing condition calculation unit calculates a photographing condition based on the photographing information. The photographing area control unit controls a photographing area based on the photographing condition. The photographing unit generates an image data by photographing the photographing area. The communication unit transmits the image data to the external projection device.
Abstract:
A light-emitting device includes a board; and light-emitting element arrays connected in parallel and each including light-emitting elements mounted on the board and connected in series. The light-emitting elements in each of the light-emitting element arrays include one or more red LED chips and one or more blue LED chips. Each of the red LED chips on the board is disposed non-successively to any other one of the red LED chips along a Y direction and along an X direction. The Y direction is parallel to a direction along which the red LED chips included in one of the light emitting arrays including the red LED chip are arranged. The X direction is perpendicular to the Y direction.
Abstract:
An illumination device is provided. The illumination device includes a substrate including a light-emitter. An instrument main body includes a substrate arrangement surface, with the substrate being on the substrate arrangement surface. A cover is attached to the instrument main body, covers the substrate, and is transparent. An antenna is on the cover and configured to receive a signal from an outside of the illumination device. A driver is on the instrument main body and configured to supply power to the light-emitter. A controller is configured to control the power supplied from the driver to the light-emitter based on the signal received by the antenna. The cover includes a diffusion factor from 40% to 90%.
Abstract:
Luminaire includes: lighting apparatus which includes a wireless communication circuit and a light emitter of which a light emitting state is controlled based on a control signal received by the wireless communication circuit; and an apparatus body to which the lighting apparatus is detachably attached in different orientations.
Abstract:
A lighting device includes: a communication unit configured to wirelessly communicate with a wireless device provided externally; a command receiver that receives a command from outside; a light emitter including a light source; and a controller connected to the communication unit, the command receiver, and the light emitter. The command receiver receives a wireless device specifying command that specifies the wireless device with which the communication unit is to wirelessly communicate. The controller tests wireless communication with the wireless device via the communication unit based on the wireless device specifying command received, obtains communication reliability information regarding the reliability of the wireless communication, and causes the light emitter to perform at least one of flashing, dimming, and toning based on the communication reliability information obtained.
Abstract:
A light-emitting device includes a board; and a first light-emitting element array and a second light-emitting element array connected in parallel and each including light-emitting elements mounted on the board and connected in series. The light-emitting elements includes a red LED chip and a blue LED chip. The red LED chip is sealed with a dot of a first sealant, and the blue LED chip is sealed with a dot of a second sealant which is different from the first sealant.
